2. Description of the Related Art In a known device (German Patent No. 2725831) which forms the starting point of the present invention, a pick-up stacking and placing device comprises a vertically movable sheet stack receiving table and a front face of the sheet stack receiving table. And a stationary device comprising a suction cup which can be raised and lowered but is fixedly arranged. Each sheet pile receiving table is provided with a clamping vehicle that runs on a fixedly laid rail and carries a clamping device,
The clamping device operates by gripping an intermediate product sheet captured by an associated suction cup. It is also configured to turn over the intermediate product sheet. In order to turn over, the suction cup can be rotated from the position "pointing down to the suction cup margin" to the position "pointing to the suction cup margin vehicle", in which case the operating rod surrounds the suction cup at a distance parallel to the axis. The operating rod rotates about the suction cup axis and can rotate with the suction cup. The edge of the intermediate product sheet sucked by the suction cup edge is first lifted from the sheet stack by the rotational movement of the suction cup, then inserted into the inside of the operating rod, further turning the operation rod and returning the suction cup to rotate. Thereby, it is put on a suction cup. It is known that a plurality of such pickup and stacking devices are arranged adjacent to each other and operated simultaneously in parallel. However, such pick-up stackers are costly to manufacture and operate, even from a functional point of view and appropriate in terms of efficiency, and also flexible from an automatic point of view. There is no. The overall cycle time of this known device is determined by the various actions that must be performed before an intermediate product unit can be removed from the device and fed to a plate press, but in practice a high degree of flexibility is required. Even if it is required, the picking up and stacking of the intermediate product sheets is still performed manually by workers. In this case, the movement speed and working speed of the worker are below the limit of the cycle time to be set. Such limited cycle times are longer than the purely physically and chemically feasible times of producing laminates, especially decorative panels, with a plate press. The physical time is, for example, the time required for pressurizing and releasing the plate press, and in the case of a plate press having a fluid pressure drive, for example, the pressure rise time is also the physical time. The chemical time is a time required for curing the synthetic resin at the time of pressing, for example, when the intermediate product sheet is a synthetic resin-impregnated paper. Of course, this also includes the time for loading the intermediate product material to be pressed and discharging the pressed laminate product.

[0004]

The technical problem in this field is that the device described at the outset has a simple construction and function in a cycle time of a plate pressing machine, that is to say the physical properties of a laminated plate. Operate at a cycle time corresponding to the cycle time, which takes into account the time required for the process and the chemical process and, of course, the time required for loading the material and discharging the pressed product from this. Is to be able to

A processing device 16 having a plurality of clamp members 9 is supported.

As can be seen from FIGS. 1 to 3, the pick-up and stacking device 7 is designed as a vehicle, which supports a processing device 16 having a suction cup 8 and a clamping member 9 as described above. ing. Further, the pick-up stacking and placing apparatus 7 is configured to be able to travel on a traveling rail extending in the arrangement direction above the thin plate stack receiving table 4 and the stacking and placing table 6 which are arranged in series. The running rail is made up of two rails 10.

As shown in FIGS. 1 and 2, a vertically movable receiving table 11 is provided connected to the collecting table 6, and the receiving table 11 is an intermediate product received from the collecting table 6. The unit 2 is delivered to the clamp / feed device 12.
Such receiving table 11 and clamp / feed device 1
2 is known per se. The receiving mounting table 11 is an intermediate product unit 2 sent out from the collecting mounting table 6 by a conveyor belt.
Is a conveyor belt that feeds the intermediate product unit 2 to both vertical edges thereof, and then feeds the plate press 3
Plate press 3 running on a rail that extends to
The intermediate product unit 2 is charged into the inside.

Each of the above members operates according to the cycle time of the press machine 3. This cycle time is an important manufacturing condition and is determined by the time physically and chemically required to manufacture a laminate from the intermediate product unit 2. The physical time is, as described above, a time necessary for pressurizing and releasing the plate press, for example, and in the case of a plate press having a fluid pressure driving device, for example, the pressure rise time is also a physical time. is there. The chemical time is a time required for curing the synthetic resin at the time of pressing, for example, when the intermediate product sheet is a synthetic resin-impregnated paper. Of course, this also includes the time for loading the intermediate product material to be pressed and discharging the pressed laminate product.

As can be clearly seen from FIG. 4, the picking-up and stacking device 7 embodied as a vehicle is a bogie 1
The truck has wheels 15 and a driving device 14 for rotating the wheels. As can be understood from FIGS. 2 and 3, the carriage 13 runs on the two rails 10 installed at a constant interval.
The rails 10 are arranged at equal intervals from a vertical plane passing through the center of gravity of the thin plate stack receiving table 4 and the stacking table 6.
A processing apparatus 1 for picking up an intermediate product sheet 1 one by one from a sheet stack on a sheet stack receiving table 4 and bringing it into a state in which it can be transported.
Reference numeral 6 includes a suction cup 8 and a clamp member 9. Processing equipment 1
6 is supported on the carriage 13 by the support structure 17 and is fixed to the carriage 13 in a range between the two rails 10.

In the embodiment shown, the sheet stack receiving table 4
Are arranged on both sides of the stacking and mounting table 6 and cooperate with two pick-up and stacking devices 7. Both pick-up stacking devices 7 can pick up an intermediate product thin plate from the thin plate stack receiving table 4 on either side of the stacking table 6 and transport it onto the stacking table 6. The cooperation of the suction cup 8 and the clamping member 9 is carried out in a known manner, and it is common to associate an auxiliary device with the clamping member 9 so that the clamping member 9 can clamp or grip the intermediate product sheet 1. However, the operation thereof will be described in relation to the operation of the apparatus of the present invention. For example, the intermediate product sheet 1 on the sheet stack receiving table 4 on the left side of the stacking table 6 in FIG.
When picking up and transporting it onto the stacking table 6, first, the picking-up stacking device 7 is moved to a predetermined position above the corresponding thin plate stack receiving table 4, and then the position of the suction cup 8 is slightly lowered to set the thin stack stack. The uppermost intermediate product thin plate 1 on the receiving table 4 is brought into contact with the edge in the transport direction (the edge on the stacking table 6 side),
Next, the suction action of the suction cup 8 is generated, and the above-mentioned edge is sucked by the suction cup. Then, the suction cup 8 is raised, and the edge of the adsorbed uppermost intermediate product sheet 1 is separated from the lower intermediate product sheet 1 with a gap therebetween. The auxiliary device (space support or spacer) is inserted into the resulting gap and the edge is held in the raised position. Next, the suction action of the suction cup 8 is deactivated, and the intermediate product sheet 1
Away from the edge of Next, the picking-up stacking device 7 is moved on the rail 10 and stopped at a position where the clamp member 9 can face and hold the raised edge of the intermediate product sheet 1. After the clamping member 9 grips the edge, the pick-up stacking device 7 is moved again on the rail 10 and stopped when the intermediate product sheet 1 reaches a predetermined position on the stacking table 6, and then stopped. The clamping member 9 releases the edge, so that the intermediate product sheet 1
Is transferred to the stacking table 6. Such an operation is repeated, and the required number and combination of the intermediate product thin plates 1
Are stacked on the stacking table 6 to form the intended intermediate product unit 2.

The formed intermediate product unit 2 is an integrated mounting table 6
From the conveyor belt, and is sent to the clamp / feed device 12 by the receiving table 11. The clamping / feeding device 12 clamps the vertical edges on both sides of the fed intermediate product unit 2, and then travels toward the plate press 3. When the intermediate product unit 2 reaches a predetermined position on the plate press 3, the clamp / feed device 12 stops, releases the clamp, lowers the intermediate product unit 2, and then returns to a position adjacent to the receiving table 11. To run.

At least one of the pick-up and stacking devices 7 has an inside-out device 18 for turning over the intermediate product sheet 1 as shown by an arc-shaped arrow in FIG. The reverse device 18 has a function of rotating the suction cup 8 as shown by a semicircular arrow in FIG. 4, and the suction cup 8 moves the edge of the uppermost intermediate product sheet on the intermediate sheet stack receiving table 4. After the suction, the suction cup 8 is rotated in the direction of the semicircular arrow.
In this state, the pick-up stacking device 7 is moved in the direction of the other edge of the thin plate. By inserting and arranging the extending auxiliary horizontal bar from the side, the intermediate product sheet can be placed on the sheet stack receiving table 4.
Above is totally flipped over.

An operator can perform a support operation at a location indicated by an arrow B in FIG. The operator can, for example, flip over the individual intermediate product sheets, so to speak, so as to form a gap which allows the support element to be inserted below the individual intermediate product sheet. This can be done automatically. The support element is, for example, a strip-shaped metal member.
